Yesterday, Amazon launched their very own music streaming service, the Amazon Cloud Player. If you're not familiar with cloud computing, the video above explains the basics pretty good. All existing Amazon customers can upload up to 5GB of their music for free. There's also the option to upgrade to a one-year 20GB plan after purchasing an MP3 album. I tried to get a closer look into the pricing options but wasn't seeing anything. You can try and find it on Amazon.
